2018 Map of Black River A-1 SE

About this map

Midnight Hill rises as the central landmark of this high-latitude terrain within the Yukon-Koyukuk region, illustrating the stark topographic character of the northern interior. The map documents a segment of the international boundary between the United States of America and Canada, where the landscape transitions across the eastern edge of the quadrangle. The grid of the Public Land Survey System, including T15n R31e and T14n R31e, provides the primary structure for this largely undeveloped territory. The lack of roads or established settlements on this 2018 survey emphasizes the isolation of the region, where the terrain itself serves as the primary record of the land. Geographic and surveying points across T15n R32e and T14n R32e define the parcels along the border, offering a precise view of this remote boundary line for researchers and collectors.
